Table 3 The effect of gender, percentage of GM soybean in the experimental diets (0%, 50%, and 100% GM soya), and their interaction on the body weights, food consumption, and conversion in albino rats. Results are represented as mean ± standard error of mean

  1. * Represent significant differences (P < 0.05) in comparison to the corresponding female groups. In each row, the mean values marked with the same superscript letter are similar (insignificant, P > 0.05), whereas those with different ones are significantly differed (P < 0.05). P > 0.05: insignificant, P < 0.05, P < 0.01 and P < 0.001: significant effect at α = 0.05, 0.01 and 0.001, respectively
